1. Self-defects
The original defects of stainless steel plates, such as surface wear, trachoma, stains, non-smoothness, and pollution, will affect the polishing performance. Defects such as matte, pollution, and stains can be post-processed, but trachoma, pitting, etc This kind of serious injury can't be polished, it can only be filled by other means, and then polished.
2, some defects on the surface of the raw material
Such as scratches, pitting, pickling and so on.
3.Material
The hardness of stainless steel plates is different, and the strong hardness of stainless steel during polishing is a certain requirement. If the hardness of the original material is too low, it is not suitable for polishing treatment. only simple grinding and polishing treatment can be performed to force the hardness. Low polishing of stainless steel products will affect the original BQ (polishing performance) of stainless steel.
4.Stretching
拉伸 In stretch polishing, we should appropriately stretch the length of the stainless steel product so that the polishing results will not be affected by deformation and small black spots during the stretching process. After deep drawing, the surface of the area with a large amount of deformation will also have small black spots, which will still affect the polishability.
5.Material factors of raw materials
If the hardness is too low, it will be more difficult to polish it during polishing. If the hardness is too low, the surface will be orange peeled during deep drawing, which will affect the polishability. For materials with high hardness, their polishability Relatively better.
